Egg beater



July 18, 1933- M. M. 1.. BURRELL EGG BEATER Filed May 2 1932 Patented July 18, 1933 UNITED STATES MATTHEW M. L. BURREIlL, OF MILHEIM, PENNSY LVANIA EGG HEATER.

Application filed May 2 This invention relates to egg heaters and has for an object to produce aheater so con structed that eggs and other materialsmay be beaten in small, deep containers, such as tum 6 blers or cups Without leavingunbeaten portions of the substance." 1 1 A further objectis to provide a beater that will be highlyefficienhquick in action, noiseless in operation, may be easily cleaned, may

be manufactured at a low cost, and. will be formed of a few simple, strong, ruggedand durable parts that will not easily get out of order.

With the above and other objects in view 1'5 the invention consists in certain novel details of construction and combinationsof parts hereinafter fully described and claimed it be ing understood that various modifications may be resorted to within the'scope of the appended'claims without departing from the spirit orsacrificing any of the advantages of theinvention. w

In the accompanying drawing forming part of this specification. J

Figure 1 is a side elevation with partsin section showing oneform of the beater.

Figure 2 is a cross section taken on the line 2-2 of Fi ure 1 showing the chain agitator in plan.

Figure 3 is an enlarged detail cross section showing the method of securing the slide to the spiral shaft.

Figure 4 is a fragmentary side elevation showing a modified form of the shaft.

Figure 5 is a fragmentary section showing a modified form of slide and shaft, and

Figure 6 is a cross section taken on the line 66 of Figure 5 showing the method of securing the slide to the shaft.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, 10 designates a grip or handle which may be formed of any desired hard substance, which is counterbored to provide an axial recess 11 which terminates at the inner end in a conical seat 12. The handle is provided with a ferrule 13 which may be secured in place in any preferred manner.

As shown in Figure 1, the spiral shaft 14:

is formed of a pair of wires twisted together longitudinally. However, the shaft may be formed,=*as shownin Figure 4, by twisting a ribbon 15 spirally. the shaft may be formed by cutting a spiral groove-16 in a rod 17, as shown in Figure 5. Regardless of the exact method of forming the shaft i'tis desirable that the shaft pass rotatably through the ferrule of the handle and terminate in aconical bearing 18 which fits in the seat12'. A ring 19' isfixedly secured to'the shaft at such a distance from the bearing as to engage theferrule13 and prevent escape of the shaft from the handle.

' The slide 20, shown in Figure 1,-is formed of a spiral length wire or other suitable materiai and is shaped so that the opposite ends flare outwardly while the ce'ntralportion is constricted. The ends 21 of the spiral are turned inwardly against the terminal convolutionsthereof. By referrin particu larly to Figure 3, will be seen that the central convolution of the spiral is flattened to substantially oblong shape and snuglyen circlesthe spiral shaft 14. The straight sides of this central' convolution by fitting close against the surface of the spiral shaft function to rotate the shaft when the spiral slide is raised or lowered.

A stop ring 23 is fixed to the spiral shaft below the slide and limits movement of the slide downwardly while the ferrule 13 limits movement of the slide upwardly.

The agitator comprises a disk 24 which is fixed to the lower end of the spiral shaft in any preferred manner, such as by soldering or otherwise, and is provided centrally with a substantially oblong opening25, as best shown in Figure 2, to permit the shaft to project through the disk and extend for substan- 9o tially a half-inch, more or less, below the disk, as best shown in'Figure 1. The disk is provided with an annular series of openings 26 which receive the inner links of short chains 27 and any desired number of these 5 chains may be employed.

The device is operated by placing the bottom of the shaft 14 and agitator into the container of the substance to be beaten. The bottom of the shaft must rest with moderate I00 pressure on the bottom of the container so that pivoting action may take place. The operator grasps the handle 10 with one hand. The slide 20 is grasped by the thumb and forefinger of the other hand and oscillated up and down the spiral shaft 14. This causes the shaft to rotate rapidly, first in one direction, and then in the opposite direction. The disk 24 and chains 27 are also rotated with the shaft. This rotation of the chains,'first in one direction, then in the opposite direction, produces a rapid and forceful whipping efifect and in turn produces the desired result effectively and in a very short period of time.

A modified form of a slide is shown in Figure :5, and comprises aspool 28 of any desired hard substance which is provided at one end of its bore 29 with a flanged bushing 30 which loosely receives the above described spirally grooved steel shaft 17. A disk 31 is disposed over the opposite end of the bore and is provided with prongs 32 which are embedded in the end of the spool. The disk is provided centrally with asubstantially square opening 33, as best shown inFigure 6, which conforms to the contour of the shaft. By virtue of the Wall of the opening 33 hugging closely the grooved surface of the shaft, when the spool is raised and lowered, it rotates the shaft alternately in opposite directions. In this embodiment of the invention the shaft is equipped with a stop sleeve 34 which limits downward movement of the spool of the slide.

In Figure 4 a modified form of bearing for the lower end of the shaft is shown to comprise a cup 35 which is provided with a slit 36 to receive .the lower end of the spiral ribbon 15 and preferably the end of the cup is conicahas shown at 37 The cup is provided with a flange 38 which is formed near the edge with perforations 39 to receive the inner links of chains 40.

The handle 10 is common to all of the forms I of the invention.

From the above description it is thought that the construction and operation of my invention will be understood without further explanation.

What is claimed is:

1. An egg beater comprising a spiral shaft, a handle rotatably receiving one end of the shaft, an agitator on the opposite end of the shaft, and a slide for rotating the shaft comprising a helical length of Wire having a convolution intermediate the ends thereof flattened to provide an oblong loop adapted to snugly conform to the contour of the shaft.

2. An egg beater comprising a-spiral shaft, a handle rotatably receiving one end of the shaft, a slide movable longitudinally on the shaft and having a. portion snugly hugging the surface of the shaft to cause rotation of the shaft, :1 cup shaped bearing enclosing the lower end of the shaft provided at its upper end. with a flange spaced above the lower end of the shaft, and link chains carried by said flange.

3. An egg beater comprising a spiral shaft, a handle rotatably receiving one end of the shaft, an agitator on the opposite end of the shaft, and a. slide for rotating the shaft comprising a helical length of wire having a convolution substantially midway between the ends of the slide flattened to provide an ob- I long loop snugly conforming to the contour of the shaft, the loops of the slide at opposite sides of said flattened loop being of graduated enlarged diameter whereby the slide is flared towards opposite ends thereof.
